The compression regulates how fast the shock compresses. If, for example, you are experiencing unwanted suspension bob on your bike, you can counteract this by adjusting the hardness of the compression. This also helps when the suspension fork compresses too far when riding down steps or bottoms out with hard shocks.

The adjusting screws for compression are often blue and located near the screws for adjusting the rebound. However, please note that the not all shocks allow the rider to adjust the compression.

The lower the compression, the more sensitive and comfortable the suspension performance will be.

Lockout

The Lockout function allows the rider to effectively switch off the shock’s compression. RockShox suspension forks allow you to activate the lockout via the PopLoc lever on the handlebar. Picture 1 Magura forks also have the Lockout lever on the handlebar. DT Swiss forks can be blocked by turning the silver knob on the top right of the fork crown.

FOX RL and RLC forks allow you to intensify the level of compression right through to total Lockout via the blue lever. Picture 2 The fork then only compresses when the bike hits extremely hard bumps. On FOX forks with RLC technology the breakaway torque can be adjusted. The breakaway torque can be adjusted via the black knob on the top right of the fork crown. If you turn the knob clockwise, you increase the trigger force that is required to make the fork compress.

High Speed und Low Speed Compression

With some RockShox and FOX models you can adjust the high speed and low speed compression separately, i.e. the speed dependent damping.

High speed compression absorbs shocks which only affect the fork very momentarily, for example roots, stones or steps. The higher the high speed compression is, the greater is the protection against bottom-out. The low speed compression, however, counteracts loads which affect the suspension for longer periods, for example when riding through banked bends, during shifts of weight or when braking. The low speed compression prevents the fork from sinking further down which would result in a reduction of travel.

You can adjust the lowspeed performance with the small screws and the highspeed performance with the bigger screws.

With FOX RC2 models you can adjust the high speed compression on the upper blue adjusting wheel at the bottom of the right-hand fork stanchion. Picture 5Picture 5 The low speed compression regulator is somewhat smaller and is positioned directly below it. Picture 6 On RLC models the blue low speed adjusting knob is at the top right of the fork crown. Picture 7

Certain Fox 36 forks and the Fox 40 have the possibilty to adjust high- and lowspeed compression. Picture 8

On other Fox spring elements you can adjust compression using CTD function.

You can set up high- and lowspeed rebound and compression on the Cane Creek Double Barrel damper. You can adjust the compression with the screws on the left hand side and the rebound with the screws on the right hand side. The screws on the right hand side are for adjusting compression. The lever is for switching on and off the climb switch fuction which suppresses pedal bobbing.

Adjustment of the Terralogic threshold

The Terralogic threshold adjuster is a blue knob fitted to the relevant FOX forks at the bottom of the left-hand stanchion.
